Yes, I'm going with a transfer system. Not being the brightest bulb on the tree I thought KISS would be the best way.
The in-line filter is a great idea. I was going to avoid removing the sending unit and internal pump if possible and who know what kind of crud is in the tank without inspecting it? A filter could prevent a lot of heartburn down the road.
As I mention the tank has and internal pump so no Aux pump to deal with.
I will also have a factory dual filler neck, I haven't seen it yet. The drawings don't look like there is a place to connect a hose from the pump. Did yours come with the pump connection or was it something you added?
